I have just fetched the latest devel version of isabelle (2fd70eb1e9b6 tip) but
cannot build isabelle because of missing components:
$ isabelle build HOL
"/Users/nipkow/.isabelle/contrib/isabelle_setup-20221028"
Error: Could not find or load main class isabelle.setup.Setup
Caused by: java.lang.ClassNotFoundException: isabelle.setup.Setup
Unfortunately, trying to download the components fails in exactly the same way:
$ isabelle conponents -a
"/Users/nipkow/.isabelle/contrib/isabelle_setup-20221028"
Error: Could not find or load main class isabelle.setup.Setup
Caused by: java.lang.ClassNotFoundException: isabelle.setup.Setup
Thus I seem to be stuck...

I have tried to reproduce the problem with Isabelle/2fd70eb1e9b6, after
deleting these components: isabelle components -a works for me as expected.
It would be interesting to know where the java.lang.ClassNotFoundException
happens: it must be somewhere in the stack of etc/settings scripts.
You can try to put "set -x" into lib/scripts/getsettings near the start, to
geta full trace (and send me that privately).
Thus I seem to be stuck...
It is always possible to download and unpack missing components manually. It
should be sufficient to do it for isabelle_setup-20221028

A typo of mine :rolling_eyes: (as Peter Gammie noticed)

OK, problem solved.
Also note that the current / more convenient way is to use Admin/init instead
of "isabelle components -a".
